abstract: Fifty-eight populations of H. glycines were collected from 10 major soyabean producing states. These populations were compared for infraspecific variation in parasitic potential on soyabean genotypes 'Peking', 'Pickett', Plant Introduction (PI) 88788, PI 90763, and 'Lee 68'. Race 3 was present in 45% of locations; it was the most widespread population. Race 6 was present in 19% of the locations. Frequency of occurrence of other races (Races 1, 2, 5, 9, and 14) ranged between 3 and 9%. On the basis of reproduction on genotypes, 83% of the populations tested had genes to parasitize Pickett. All populations from Arkansas, Florida, Georgia, Iowa, North Carolina and South Carolina produced cysts on this genotype. Average level of parasitism was greatest on Pickett and lowest on PI 90763; 91% of SCN populations tested had <10% level of parasitism on PI 90763. The SCN gene frequencies demonstrated that nematode populations with predominant genes for parasitism on Pickett and Lee 68 were widespread especially in the southern soyabean producing states in the USA. Cultivation of varieties with resistance derived from Peking and Pickett in these regions should not be very effective. For management of SCN-caused yield losses, cultivation of soyabean varieties with resistance derived from PI 90763, PI 88788, and PI 437654 should be encouraged.
